The 'pear' command is now at your service at /usr/bin/pear

** The 'pear' command is not currently in your PATH, so you need to
** use '/usr/bin/pear' until you have added
** '/usr/bin' to your PATH environment variable.

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.
